For 35mm film, that’s going to be functionally the same as using the full-frame option in the calculator above. I haven’t added other film sizes, but I might try to put together a separate calculator for that.

Olympus and Panasonic Lumix are the most prominent manufacturers using this sensor format. In practice, there can be very slight variations in the dimensions of the sensors from model to model.

Here’s a calculator for the angles of view from lenses on digital camera sensors, as well as angle of view charts for common focal lengths. And I’ve also included an explanation of why the diagonal angle of view matters more than you might think.

The data here is calculated. For more specific data that applies to a particular model of lens, check the manufacturer’s spec sheets for that lens. Sometimes there might be, say, a half degree of variation, but in general, these rounded numbers should get you very close. I’ve compared them with a number of lens spec sheets and found the data here to be quite accurate.

Knowing the angle of view gives you a baseline reference for how wide a perspective you can fit in the frame. In a practical sense, I find it useful for choosing which lens is right for the job.

The same general principles apply for film, but instead of using the size of the sensor you’d use the size of the exposed film plane.

When you’re taking photos, the angles of view horizontally or laterally across the frame or vertically up and down the frame are probably the ones you’re most focused on. But it’s actually the diagonal measurement that comes up more often.

This is for full-frame digital cameras with a sensor that measures 36mm x 24mm, which is the convention for a full-frame sensor. It also applies to SLR cameras using 35mm film.

By having a reference point you can compare lenses in an apples-to-apples kind of way. That can be very handy when choosing the right lens for the job.

An easy example is when shooting architecture or landscapes. For those, you often might want to be able to fit quite a wide perspective, or large angle of view, in the frame.

When you see that a lens has so-and-so degrees angle of view, it’s actually telling you it’s from one corner to the diagonally opposite corner. It’s not telling you the angle of view from side to side.

The reason I’ve singled Canon out as a special case here is that Canon’s APS-C sensors are just a smidgeon smaller than most other APS-C sensors.

A larger angle of view corresponds to a wider lens, meaning you can fit more perspective within the frame. Conversely, a smaller angle of view gives you a narrow perspective, as you might get with a telephoto lens.

That’s because it’s the spec that lens manufacturers include in their spec sheets. So when you see that a lens has so-and-so degrees angle of view, it’s actually telling you it’s from one corner to the diagonally opposite corner. It’s not telling you the angle of view from side to side. In that respect, it’s a bit like the size spec that TV manufacturers use (i.e., a 55-inch TV is 55 inches from one corner to the diagonal corner, not from one side to the other side).

Yes, this angle-of-view calculator works for zoom and prime lenses. You can enter any single, specific focal length along the zoom range. For instance, for a 24-70mm zoom lens, you can enter 55mm to see the angle of view at that point in the zoom range.

It’s also a fixed reference point if you’re using the same or similar focal lengths but on different-sized sensors. For instance, a 20mm lens will give you a wider angle of view on a full-frame camera than on a Micro Four Thirds camera.

Among the items found within Topaz' next were a bundle of straw, a magnifying glass, a single gold coin and a unique key.[1]

The practical angle of view of a lens varies based on the camera’s sensor size, so I’ve included some of the most common sensor sizes.

These charts offer an alternative way of visualizing the calculated data above. It might be useful if you’re approaching it from the other direction and trying to find a lens that has a particular visual coverage that you’re after.
